Chemistry in Confined Spaces

Welcome to Sashuk's Group !

Molecules are like humans - are born and die, get married and divorced, and when imprisoned do not give up but change their behavior.

Our research is mainly focused on the study of confined matter. We wonder how the chemical entities are affecting or being affected by the confined environment they create. In particular, we are interested in harnessing their modified properties for catalysis or self-assembly by translating them from the molecular level onto nanoscale (or even further) and vice versa. The confined systems we are currently dealing with include molecules and colloids entrapped by supramolecular cavities or self-assembled at interfaces.
